character whereby a powerful blow may be swAGINeM-MACHINEAFOR ARTIFICIAL DENTURES.

1` Application led February 7, i925. Serial No. 7,583.;` v

invention relates to swaging machines, and my object is to provide a simple, compactv and relatively inexpensive machine kof this delivered for swaging erownsyinetal plates and other articles pertaining` to articial denture. l i Y In order that the invention may, `be fully understood, reierencewill now be hadto the accompanying drawings, in which: Fig. lis a vertical sectional view of the machine. n v f Fig. 2 is a! plan view of the machine.

' Fig.` 3 is a.v transverse sec/tionen line Iii-III of Fig. i.

In carrying out the invention, I 'employe i relatively heavy base 2, which may if desi-red v be bolted or otherwisesecured to a work bench `or other substantial support.`

4 designates aV pair of verticallyfdisposed guide rods, which` are securedtat their lower ends to the base 2 andV united at their upper ends by. a` yoke 6 having a central bore 8 freelyiextends. The yoke 6 has a feat-her 7, which projects into agro'ove 9 extending lonf gitudinally :of the screw] 10 to vprevent the same from rotating. Y Y

l2 designates a bevel gear threadedupon the screwlO and constituting a nutor adjusting said screw up and down. The bevel.

gear l2 intermeshes with a bevel gear 14 tiXedly-i'nounted upon a shaftflG' journaled in abearing l8vp-rojecting upwardly from the yoke 6. rlhe shaft 16 is also provided with a liXedly-niount-ed fly wheel 20, which r may be rotated clockwise and anticlockwise, *by suitable means, such, for instance, las' ahandle22. Y' Y` v The lower end of thescrew lOvrisprovided with a trip-lever 24 connectedthereto by a pivot 26 and provided at its lowerv end with an antifrictioii roller 28, for a purpose which will hereinafter appear.

Y 30 designatesan adjustable stop threaded in the yoke 6 and depending into the path of the trip lever 24 to cause .the same to rock on itslpivot 26 and releasea verticallymovlable rain 32 ofsuitable weight, and provided atfits upper portion with van integral cross head 34, reciprocably mounted on the guide rods 4 and provided at its upper portion with a hook 36 adapted to engageY over the antifriction roller 28. l

Coil'springs 40 loosely 'embracing the guide iods 4,l are interposedwbetween theV yoke 6 Aand lthe Vcross head 34 to torce the saine andthe f ram 32 downwardly and cause said ramto i deliver a powerful blow upon any article placed upon .the base2, which has a pocket 44 containing a suitable :shock absorber 42,'such, for instance, as ground cork, to prevent undue shock being' imparted to thesupportupon which the machine rests. ,e

46, designates acontainer which i'sjieinovably seated upon, the shoclriabsorber42 and n Y- adapted to hold a die or model with the arf` Y ticle/to be swaged thereon; In Fig. 1,1 `have swaged upon al model A, which isembedded which distributes the forceofthe blow from the rain 32 uniformly over the plate I5. The t Container 46 yisprovided with a removable bottom' 48 and a metal or other substantial In practice lthe rain 32 is raised a. suitable distance togive access to the pocket 44 byeiigaging the roller 28 under t-he hook 36 and raising theserewl 10b-y opcrating'the ily wheel Iollowerplate 50 covered kwith a leather or f Aother.suitablecushion 52. through which a vertically-disposed screw 10 v2O and the beviel gears 14 and l2.l The model in thecontainer 46 and surrounded with the putty 'C upon which the follower plate v50 is' 'A'and the metal plate I3 are then placed .withcontainer 46. The screw 10 is then raised as before' and carries tl enpper end of .the trip lever 24 vagainst the stop 30, which, cooperates with the upwardly inovingscrew lOin roeking the trip lever 24 upon its pivot 26 v'to the dotted position Fig. l,V thereby causing the roller 28 tofrelease the hook 36.", The relatively heavy raml 32 then descends by the torce of gravity Aand the r'action of the coil' springs 40 andfstrilres a heavypblow upon-the e follower plate 50, the torce of the blow caus# ing:r the putty C to shape the metal plate B to the model A. Asthe ram 32impinges against the follower4 plate 50, or' rather vits leather VVcushion 52, shock to the workbenchV i l or other support is reduced to a. minimum c through the intermedjacy of the shook ab'- sorber 42; Aiterthemetal plate. B has been properly tted tothe model A, the container" V46 is removed from the picket 44 and inverted, so that pressure may be applied to the bot tom 48 to cause the same to force the putty C, together with the model A and plate B from the container 46, the bore of which tapers towards its upper end so that its contents can be readily removed when it is inverted as stated.

The upper surface 56 of the hook 36 is of sloping formation, so that when the screw l() is lowered the roller` 28 will Contact and be guided by said upper surface into the cavity 58 of the hook 36, so that the ram 32 may be again lifted preparatory to delivering another blow.

From the foregoing description it is apparent that I have provided a machine embodying the advantages above pointed out,

' and while I have shown and described the preferred construction, combination and arrangement of parts, I reserve the right to make'such changes as properly fall within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent,

ing said ram and means for disengaging said raising means from the ram so that the same may descend and deliver a blow to an article on the base of the machine.

2. A .machine of the character described consisting of suitably supported vertical guides, a member uniting the upper portions of said guides, a screw extending vertically through said member, mechanism including a rotary element threaded upon said screw for moving the same up and down, a ram mounted to move up and down on the guides, and a trip lever mounted on the screw for raising the ram and then releasing the same so that it may descend.

3. A machine of the `character described consisting of a base, a guide extending upwardly from said base, a yoke at the upper `portion of said guide, a screw extending vertically through said yoke, manually-controlled mechanism including a rotary element threaded upon said screw for moving the screw up and down, a ram operably mounted on the guide, means carried by the screw for raising said ram, and a member adjustably mounted in the yoke and adapted to disengage said raising means from the ram so that the same may descend.

4. A machine of the character described consisting of suitably supported vertical of said guides, a screw extending vertically through said member, mechanism including a rotary element threaded upon said screw for moving the same up and down, a ram mounted to move up and down on the guides, a trip lever mounted on the screw for raising the ram and releasing the same so that it may descend, and spring means interposed between said ram and the member uniting the upper,

portions of the guides for accelerating the descent of the ram.

5. A machine of the character described consisting of a base having a pocket, shock absorbing means in said pocket, guides extendin upwardly from said base, a yoke unitii the upper ends of said guides, a screw e.` ending vertically through said yoke, mechanism including a rotary element threaded upon said screw for moving the same up and dew i, a ram oper-ably mounted on the guides, and means carri-ed by the screw for raising said ram and then releasing the same so that it may descend and deliver a blow upon an article resting upon the shock absorber.

6. A machine of the character described consisting of suitably supported guides, a member uniting the upper portions of said guides, a screw extending vertically through said member7 a gear wheel threaded upon said screw for raising and lowering the latter and resting upon the member uniting the up# per portions of the guides, a second gear wheel for rotating the first gear wheel, a shaft upon which said second gear wheel. is fiXedly mounted, manually-control]ed means for rotating said shaft, a rain mounted to move up and down on the guides, and a trip lever mounted on the screw for raising the ram and then releasing the same so that it may descend.

7. A machine of the character described consisting of a base, guides extending upwardly from said base,` a yoke uniting the upper ends of said guides, a screw lextending vertically through said yoke, mechanism for moving said screw up and down, a ram having a cross head slidablyengaging the guides, a hook in the upper endof said ram, a trip lever carried by the screw for engaging said hook and raising the ram, and a member threaded in the yoke for disengaging said trip lever from the ram so that the same may descend. l i Y In testimony whereof I aliixmy signature.
